Math question: What is the smallest prime factor of the number 742?

To find the smallest prime factor of 742, we divide it by prime numbers starting from 2. When divided by 2, we get 371, which is not divisible by 2. Dividing it by 3 gives us 247. By successively dividing it by 5, 7, 11, 13, and so on, we find that the smallest prime factor is 17. Hence, the smallest prime factor of 742 is 17.

What is the sum of the digits of the number 742?

To find the sum of the digits in 742, we add the individual digits together: 7 + 4 + 2 = 13. Therefore, the sum of the digits in the number 742 is 13.

Math question: What is the sum of the prime factors of the number 742?

To find the prime factors of 742, we prime factorize it as 742 = 2 * 7 * 53. Now, to calculate the sum of these prime factors, we add them together: 2 + 7 + 53 = 62. Therefore, the sum of the prime factors of 742 is 62. Prime factorization helps break down a number into its prime constituents, allowing us to analyze and understand it better. In this case, 742 can be expressed as the product of its prime factors, which sum up to 62.
